TauSpinner for Spin and New Physics in Tau Pair Production
Analysis
This paper presents an extension to the TauSpinner program, a Monte Carlo tool, to incorporate spin correlations and New Physics effects, specifically focusing on anomalous dipole and weak dipole moments of the tau lepton in the process of tau pair production at the LHC. The ability to simulate these effects is crucial for searching for physics beyond the Standard Model, particularly in the context of charge-parity violation. The paper's focus on the practical implementation and the provision of usage information makes it valuable for experimental physicists.
Key Takeaways
- •The paper extends the TauSpinner program to include spin correlations and New Physics effects in tau pair production.
- •It focuses on anomalous dipole and weak dipole moments of the tau lepton.
- •The implementation allows for arbitrary phase-shifts between vector and axial-vector couplings.
- •The paper provides information on how to use and configure the TauSpinner program.
